Dealing With a Smelly Garbage Disposal

A garbage disposal is a useful kitchen appliance, but it can develop an unpleasant odor due to food particles remaining on the walls of the grinder.  Bacteria growing in the bits of food left behind create unpleasant odors in garbage disposals.  Here are few simple tips for dealing a smelly garbage disposal.

To get rid of garbage disposal smells you want to do more than just mask the odor.  You need to clean the leftover food particles from inside the unit.  Running a few ice cubes through the disposal will help knock loose stubborn food particles and scour the inside of the disposal and blades.  Making the ice cubes out of vinegar is even more effective.

Flush away the loosened particles by filling the sink with six inches of soapy water, then unplug the sink and run the disposal while the soapy water drains.  A common household plunger works well to stop up the drain to fill the sink with water.

Another method is to cut up a lemon or orange and run it through the disposal.  The citrus juices will help clean the disposal and leave fresh clean scent.

To help keep your garbage disposal clean, be sure to run plenty of water through the disposal when grinding up waste.  Also, be sure to allow the disposal to run long enough to dispose of all the waste.  Not running the disposal long enough is a primary cause of garbage disposal smells.

Finally, avoid pouring grease and oil down the drain.  Grease and oil will accumulate on the walls of the disposal and the drain pipes and cause odors.  If you must dispose of small amounts of grease or oil, run cold water to help prevent the grease and oil from adhering to the drain pipe and the disposal.

Taking Care of Your Garbage Disposal

A garbage disposal is great to have in the kitchen, but it will frequently jam or break down unless it is used and cared for properly. You can avoid expensive garbage disposal repairs by following a few simple guidelines.  If you take good care of your garbage disposal, it should give you years of trouble free service.

One of the biggest mistakes people make with garbage disposals is not grinding long enough and turning off the water too soon.  Both of these practices result in food particles remaining in the disposal that will soon decompose and cause unpleasant odors.

Always run plenty of cold water when grinding and let the grinder run until grinding is complete.  Turn off the garbage disposal off first and let the water run for an additional 15 seconds to thoroughly flush away the food particles.  Avoid disposing of grease and oil down the drain and use cold water rather than hot water.  Hot water liquefies fats and oils and allows them to adhere to the walls of the grinder and drain pipes. Cold water encourages fats and oils to coagulate so they can be flushed away.

Run some soapy water through the disposal daily and grind up a few ice cubes once or twice a week to help break up accumulations of food particles inside the disposal.  Grinding a lemon or orange once a week will also help keep the disposal clean and fresh smelling.

Never grind anything that is not a biodegradable food substance.  Garbage disposals are designed to grind food only and cigarette butts, bottle caps, and other materials can cause serious damage to your garbage disposal.  Never put your hand into a garbage disposal to clean it or to retrieve an item unless the power is turned off at the circuit breaker.

Garbage Disposal Size

Garbage disposals are a useful item to have in the kitchen.  They reduce food waste that would otherwise go into the trash and since they grind food waste into small particles, they reduce kitchen sink clogging.  When shopping for a new garbage disposal, you will need to choose how much power you need.

Garbage disposals are sized by the horsepower of the motor.  Smaller disposals are 1/3 or 1/2 horsepower and larger units are 3/4 or 1 horsepower.  All else being equal, higher horsepower means quieter, faster, and smoother operation.  In addition, since a high horsepower model doesn’t have to work as hard to grind up food waste, it will typically last longer than a lower horsepower model.

Higher horsepower disposals can handle hard to grind waste like bones or fibrous waste (think celery) much better than smaller units that become jammed or clogged by these materials.  Lower horsepower garbage disposals are best suited for smaller households and for light duty use.  If you cook infrequently and don’t plan to grind bones and other tough food wastes, a 1/3 horsepower or 1/2 horsepower disposal will probably do the job just fine.

On the other hand, if you cook frequently at home, have a large family, and want to put almost any type of food waste through the disposal, a 3/4 horsepower or 1 horsepower model would be a better choice.  Not only will the disposal be able to handle the load, but since you will be using it frequently you will appreciate the smooth, quiet, jam-free operation.

Garbage Disposal Types

When choosing a new garbage disposal for your kitchen you will have several options to choose from.  In addition to the size of the motor, you will need to choose between a batch feed model and a continuous feed model.  Each type of garbage disposal has its advantages and disadvantages.

Continuous feed models are the most common type of garbage disposal.  With a continuous feed model the disposal is switched on and keeps running until it is turned off.  While it is running, you can continue adding waste material.  Alternatively, you can choose to add the waste material, switch on the disposal, and then switch it off when the grinding process is complete.  Water should be running while the unit is in operation to help flush away the ground up waste.

With a batch feed model, the waste material is loaded into the disposal and a lid or cover is locked in place over the drain before the unit switched on.  On some units, installing the lid or cover activates the disposal.  On others, the unit is turned on with a wall switch like a continuous feed model.  In either case, the disposal will not operate without the lid or cover in place over the drain.

The main advantage of a batch feed model is that it is safer than a continuous feed unit.  Since a batch feed disposal will not operate without the lid in place, it prevents hands and fingers from accidently getting into the disposal.

Continuous feed models are a little faster than batch feed models, especially if you have a large amount of waste material to dispose of.  Some cooks prefer continuous feed models because they can leave the unit running while they are handling food preparation like chopping and peeling.

Whichever model you choose, your garbage disposal installation is best handled by a good local plumber.  Professional garbage disposal installation helps ensure that the unit will work well, won’t leak, and will provide good service for years.

Garbage Disposal Maintenance

Most garbage disposals are robust kitchen appliances that work for years with little or no maintenance. However, a jammed, clogged, or otherwise malfunctioning garbage disposal can mean calling your plumber for garbage disposal repairs.  There are  a few things you can do to keep your garbage disposal working great and avoid that expensive repair call.

First, you should always run cold water down the drain into the disposal while the unit is grinding and for five to ten seconds after you turn it off.  Running water helps flush the ground material down the drain and through the drain lines.

Cold water is better than hot water because it will help fats and oils congeal so they can be flushed away.  Hot water will cause fats and oils to liquefy and they can end up lining the walls of your drain line which will eventually lead to a clog.

Avoid putting high fiber waste material like corn husks or celery stalks down the disposal.  These can clog even a heavy duty waste disposal.  Don’t overwork a light duty disposal by putting bones down it or running it continuously for more than a few minutes.  Small disposals are not designed to handle these types of loads.

Never put glass, metal, plastic, or any other non-food material down the disposal.  Not only can it be dangerous, but these materials will jam or completely ruin the disposal.  Finally, you can help rid the disposal of food deposits and odors by grinding egg shells or small amounts of ice.  Your disposal will work better, smell cleaner, and last longer.

Septic Garbage Disposals

There are a wide range of opinions about using a garbage disposal if you are on a septic system.  These opinions range from those who maintain that garbage disposals should never be used on a septic system to those who believe that garbage disposals actually help septic systems work properly.

It can be a challenge to make sense of these conflicting opinions, but EPA research indicates that garbage disposals place an additional burden on septic systems.  The best answer is probably that most properly sized and maintained septic systems can handle this extra load imposed by use of garbage disposals, especially if the homeowner has the septic tank inspected regularly and pumped when needed. About a quarter of the 27 million residential septic systems in use in the United States have garbage disposals and there is no empirical data that shows a significantly higher rate of septic system failure with these systems.

Not surprisingly, most garbage disposal manufacturers take the position that garbage disposals do not harm septic systems.  In fact, some disposal manufacturers market garbage disposal models specifically designed for use on septic systems.  These disposals work just like conventional garbage disposals except that they have a cartridge attached that injects natural microorganisms into the drain whenever waste is ground.

These microorganisms help break down the food waste and reduce the level of solid material in the septic tank.  Other than having to replace the cartridge every few months, these special septic models don’t require any additional maintenance or care than a conventional model.  A reputable plumber who handles kitchen repairs can help you choose and install a great new garbage disposal.

Choosing a Garbage Disposal

A garbage disposal can be a handy item to have in the kitchen.  Garbage disposals grind up kitchen scraps and flush them down the drain.  While this results in reduced amounts of garbage, garbage disposals impose and extra burden on sewer and septic systems.  If you are on a septic system, be sure to have your system evaluated by a sewer-septic professional to be sure your system can handle the increased volume of waste and water generated by a garbage disposal.

When choosing a garbage disposal, your first consideration is how much power you need.  The smallest disposals are 1/2 horsepower and are fine for light duty and small households.  If you anticipate heavier usage, consider a 3/4 hp or 1 hp model.  These heavier duty units can handle large amounts of kitchen waste and will jam less frequently.

Garbage disposals are made in two basic types:  continuous feed and batch feed.  Continuous feed disposals are easier to use because you can keep feeding new waste into the unit as it grids up the old waste.  However, continuous units have open drains and are more hazardous because a hand or finger can get into the unit while it is running.

Batch feed units take longer because they have to be loaded and fresh waste cannot be fed into the unit until the previous load has been ground and flushed.  However, they will not run without the stopper in place so they are safer than continuous feed units.

Installation of garbage disposals requires some knowledge of plumbing and electrical work.  If you are not comfortable installing the garbage disposal, you should leave the job to a reputable local plumber with experience in kitchen repairs and garbage disposal installation.
